I have a blog installed on my site using Wordpress. Last week I upgraded Wordpress from 2.6 to 3.0.4 (I had to do this manually).

All went well, or so I thought, but I have just noticed that the content of an existing page has vanished. The page URL still works, but all content has disappeared - doctype, html tags, body tags, everything.

Please note, this is specific to pages - posts are still displaying fine.

I have since created a brand new page which does not display the content either.

Things I have tried include

Switching to a freshly installed theme

Deactivating all plugins

Setting the problem page to draft, and back again

Deleting the .htaccess file

I suspect it's a database problem and have contacted my hosting company who have said the only thing they can do is restore the DB from a backup, but that I should consider it a last resort.

I have a similar issue. The them is well installed and looks great. But the content on pages and post do not appear when you preview the website. You can only see them in the dash board. Can anyone help?
my website is http://a-1duicounselingservices.com/

Unless the accepted answer here solves your problem I would suggest asking your question in its own right. Adding it here as an 'answer' in an already answered question means not many people will see it.
